Yes, Quixtar is the new corporate name for what used to be Amway. I have no desire whatsoever to be visited by their salespeople, so I order online, about once a year. The 150-load box of SA8 I ordered last August still has about 10 loads left. I use it only for loads of highly-stained loads of whites. For everything else, I use Persil, Ariel, Tide With Bleach, Tide Coldwater, Tide HE, Viva and Ace. Oh, and Cheer For Dark Colors for black loads.
I have to say I'm sold on Quixtar's laundry line. And you'll notice they wasted no time promoting the fact Consumer Reports rated SA8 #1 in a recent detergent test (see the front of the box of SA8 in the photo, above). Now I'm getting curious about their (again, expensive) fabric softener. See if it's really any better/different than what's available on store shelves.
My weekend plans changed abruptly, so I'll be around the house. I'm going to wash curtains, couch covers, all bedding, rugs. I'm in the mood for a lot of washer action.
